Hello I have an XPS 15 L501x with I3 420m. For some strange reason the video output stopped working today.
It just flashes with a corrupt image. The port cant be broken as when I put the resolution down to 800x600 it works just fine. I have tried different HDMI cables on a differnt TV there is no display at all.)
I have used windows restore to go back to an earlier stage and also uninstalled and reinstalled nvidea drivers.
What could be the problem?
